摘　　要：研究三轴汽车的转向控制方式.通过建立三轴汽车全轮转向二自由度模型,推导三轴汽车全轮转向系统的动力学方程;运用数值仿真方法,研究三轴汽车全轮转向,前、后四轮转向,前轮转向等不同转向方式下的稳态横摆角速度增益,以及相同转向方式下中轴相对于质心的纵向距离对稳态横摆角速度增益的影响.仿真结果表明,三轴汽车全轮转向是最好的选择.To study the steering for a three-axle vehicle, a two freedom model is used to describe the all-wheel steering scheme of the vehicle. Based on the model the dynamic equations are developed. On the three cases viz.： all-wheel steering, four-wheel steering and front-wheel steering, the steady part of the yaw velocity gains of the vehicle are separately analyzed. Influence of the longitudinal distance between the middle axle and the mass center on the gains is studied. Simulation results showed that all-wheel steering scheme is the best choice for use in the three-axle vehicle.
